Meet Pseudotsuga menziesii, also known as Douglas Fir, the largest member of the Pinaceae family and one of the world's most important timber trees. Its useful wood and quick growth make it a crop of choice for many timber companies, which typically replant clear-cut areas with Douglas Fir. This evergreen conifer species is native to western North America and is planted as a specimen tree or in mass screenings. Its popularity extends to being a popular Christmas tree. The species is consumed by grouse and by deer and elk, with birds and mammals eating the seeds. It is also an extremely important food for small mammals such as mice, voles, shrews, and chipmunks, which consume about 65% of a Douglas Fir seed crop following dispersal in western Oregon. Douglas Fir is widely distributed from central British Columbia southward to central California and from the eastern edge of the Cascades west to the Pacific Coast Ranges and Pacific Ocean. Its range is continuous from near sea level along the coast to 6,000 ft above sea level in the California Mountains. Give your landscape that evergreen conifer touch with Pseudotsuga menziesii or enjoy its pleasant presence as a Christmas tree.
